IMPROVEMENT IN THE MANUFACTURE OF BA LLS AND ROSETTES 0f YARN- Specification forming part of Letters Patent No. 177,194, dated May 9, 1876 applicationfiled March 10, 1876.

To all whom it may concern:

Be it known that I, OSCAR BOEHME, of Philadelphia, Pennsylvania, have invented an Improvement in the Manufacture of Balls or Rosettes of Yarn, of which the following is a specification:

My invention relates to certain improvements in the manufacture of balls, tufts, or rosettes of yarn; and the objects of my improvements are, first, to facilitate the manufacture of goods of this class, and, second, to impart to them ornamental designs. These objects I attain in the manner which I will now proceed to describe,.reference being had to the accompanying drawing, in which Figure 1 is a view of a worsted ball or tuft of the class to which my invention relates;

Fig. 2, a sectional view, illustrating my improved apparatus for facilitating the manufacture of the balls; Fig. 3, a sectional view of the apparatus used for making figured balls; and Fig. 4, an end view of part of Fig. 3.

Balls of yarn of the character shown in Fig. l are produced by tightly binding at intervals a mass of threads, which are out between the pointswhere they are bound, as shown by the dotted lines 00, Fig. 2, when, owing to the nature of the yarn, the threads thus bound together maybe readily made to assume a spherical form.

The binding of the threads has hitherto been effected while they are loose or merely held in the hand of the operator, and after the balls were thus made they frequently presented a ragged appearance, and required subsequent trimming. This difficulty I obviate by the use of a funnel-shaped tube, A, Fig. 2, into the flaring end a of which the threads from the spools enter, and from'the contracted end b of which they pass in the proper condition for being bound. By this device the threads are firmly held and evenly delivered, and when bound and out form perfect balls, without resorting to trimming. When the threads are cut at a point close to the binding a rosette or tuft will be produced, the expansion of the several threads being confined to one side only.

In making balls which are to be attached to cords, I prefer to separate the strands of the cord B, to which the ball is to be at tached, and to bind the threads by means of these separated strands, as shown in Fig. 2, the result being a much firmer attachment of the ball to the cord than when the latter pacslses through the ball and is knotted at the en When ornamental figured balls or tufts have to be produced, I use,-in connection with the condensing-tube A, a reed-plate, D, which consists of a ring, at, adapted to the flaring mouth ofthe tube A, and provided with a number of bars or wires, 6 0, arranged at right angles to each other, so that the entrance to the tube A is separated into a number of spaces, through each of which a number of threads pass.

By properly arranging the colored threads as they pass through the reed-plate, balls or rosettes with patterns of any desired character can be produced, for, owing to the even condensation of the yarns by the tube A, theyv must all bear the' same relation to each other as they pass out at the end b that they did when they entered at the end a" By having a greater tension upon some of the threads than upon others, figures or patterns in relief may be formed on the balls or. rosettes.

I claim as my invention 1. As an improvement in the manufacture of balls, tufts, or rosettes of yarn, the mode described of first condensing the threads, and then binding and severing the same, as set forth.

2. The combination of the condensing-tube A with the reed-plate D. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
